We look at the division of 99915080 by 459 
Our goal is to divide 99915080 by 459.

Advancing to step 1:
When dividing 9 by 459, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 459

On to step 2:
When dividing 99 by 459, we get 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Include the next digit (9) from the dividend after 99, then repeat: 999 / 459

Let's proceed to step 3:
If we divide 999 by 459, we get 2 and a remainder of 81.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 918 from 999, we get 81.
Grab the next digit (1) from the dividend, add it to 81, then carry on: 811 / 459

Going ahead to step 4:
If we divide 811 by 459, we get 1 and a remainder of 352.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 459 from 811 and we're left with 352.
Append the next digit (5) from the dividend to 352 and continue with: 3525 / 459

Step 5:
When dividing 3525 by 459, we get 7 with a remainder of 312.
Use 7 as the next digit of our solution. 
Result so far: 217.0
Subtracting 3213 from 3525 leaves us with 312.
Include the next digit (0) from the dividend after 312, then repeat: 3120 / 459

Step 6:
If we divide 3120 by 459, we get 6 and a remainder of 366.
The next digit of our result is 6. 
Result so far: 2176.0
Subtracting 2754 from 3120 leaves us with 366.
Include the next digit (8) from the dividend after 366, then repeat: 3668 / 459

Moving on to step 7:
When dividing 3668 by 459, we get 7 with a remainder of 455.
The number 7 becomes the next digit in our result. 
Result so far: 21767.0
Subtract 3213 from 3668 to get 455.
Append the next digit (0) from the dividend to 455 and continue with: 4550 / 459

Let's proceed to step 8:
459 can be fit into 4550 9 times, resulting in a remainder of 419.
Put 9 as the next digit of the answer. 
Result so far: 217679.0
If we take 4131 away from 4550, we end up with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 9:
4190 divided by 459 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 217679.9
Subtract 4131 from 4190 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 10:
The number 459 fits into 590 1 times, leaving a remainder of 131.
Write down 1 as next digit of the result. 
Result so far: 217679.91
Subtracting 459 from 590 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Let's proceed to step 11:
The number 459 fits into 1310 2 times, leaving a remainder of 392.
Put 2 as the next digit of the answer. 
Result so far: 217679.912
If we subtract 918 from 1310, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Let's proceed to step 12:
When dividing 3920 by 459, we get 8 with a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 217679.9128
If we take 3672 away from 3920, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Step 13:
When dividing 2480 by 459, we get 5 with a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 217679.91285
Subtract 2295 from 2480 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 14:
If we divide 1850 by 459, we get 4 and a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 217679.912854
If we subtract 1836 from 1850, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 15:
140 divided by 459 is 0 with a remainder of 140.
Put 0 as the next digit of the answer. 
Result so far: 217679.912854
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 16:
459 can be fit into 1400 3 times, resulting in a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 217679.91285403
If we subtract 1377 from 1400, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 217679.91285403 and a remainder of 2.3e-08.
